How to Use Your
CASTLE "777” SPEED-CLAVE
WILMOT CASTLE COMPANY
STEP-BY-STEP OPERATING PROCEDURE
NOTE: Your Speed-Clave uses alternating current (A.C.) only .
1 . Open the door by throwing handle to the left, and then pushing door
slightly to the right against spring tension. Swing door out and to the
right. (Closing is the reverse of this procedure.)
2 » Pour water directly into Speed-Clave outer chamber before using.
When empty this will take 12 ounces. After each cycle, add sufficient
water (a small cupful) to bring the level one quarter of the wav up the
curved rim inside the door. DO NOT OVERFILL. Use distilled water
when available .
3 * Load. See procedure on last page for handling instruments and
4 . Push safety valve handle (B) all the way down closing the valve.
5 . For initial operation, turn bakelite knob (C) on top of control box to
left all the way. This knob controls the operating temperature in auto-
clave. (When once adjusted for desired temperature, it is not necessary
to turn this knob except to change operating temperature.)
6 . Set the timer-switch (D) between 15 and 30 minutes. This starts the
heater, and the red light (E) will come on.
Steam will now begin to form in the autoclave. It will fill the inner and
outer chambers and will expel all the air. You will notice the mixed air
and steam escaping from the vent at the rear of the autoclave. When all
the air is out. this vent will close automaticallv.
Steam pressure and temperature will now begin to show on the gauge,
and will build up quickly. Total time from start, (i.e. activating of timer),
is 7 to 8 minutes if autoclave is cold, 3 to 4 minutes if it’s hot.
7 . When the needle on the gauge reaches the desired sterilizing tem-
perature, turn the knob (C) very slowly to the right (clockwise) until
the white light (A) comes on.
Once you wake this adjustment , you wont have to turn the knob again
when you use the Speed-Clave unless you want to change the sterilizing
temperature. See Page 4 for a table of recommended sterilizing temperatures
and time periods.
8 * Re-set the timer-switch (D) for the correct sterilizing time period
(from table on Page 4).
While the autoclave is sterilizing, the red and white lights will alter-
nate. This shows that the temperature is being regulated automatically.
9 . When the sterilizing period is completed, current turns off auto-
matically, and no light will show.
10. You can let the steam pressure return to zero by waiting about 4
minutes, or you can release it immediately by raising the safety valve
handle (B). By raising this handle about l A " steam will escape slowly.
i 1 . When the needle on the pressure gauge is at zero, crack the door by
swinging the handle 90° to the left. Let the vapor escape for 3 to 5
minutes. The longer this period the drier the contents. Then open the
door* by swinging handle fully to left, pushing door assembly slightly
towards hinge and pulling outwards.
Do not leave door closed tightly when Speed -Clave is not in use. Open , or
''crack" door while Speed-Clave is still warm.
LITTLE THINGS THAT MAY BE HELPFUL
IN RUNNING YOUR SPEED-CLAVE
Read operating instructions carefully and make sure operating
personnel follow them.
If red light does not light, check electrical outlet, bulb and timer, and
see that control knob is turned to left.
If needle on pressure gauge does not “zero,” remove glass and adjust
recalibration screw so that needle points to zero when sterilizer is cold.
If contents are damp on removal, allow' longer wait after door is
“cracked” w'hen pressure is released.
Air vent in back w'ill steam for 20 to 60 seconds to insure evacuation
of all air. See that handle (B) is down.
If door closes too stiffly, lubricate bearing edge of handle w ith vase-
line. Wetting the bottom suction cups will prevent sliding.
If door should leak at rim, be sure door is centered w'hen closing. Do
not fill with w'ater more than quarter wav up curved rim.
Do not assume door gasket needs replacement unless it is visibly
broken. Replacement by qualified service man only.
A steam “whisper” at safety valve is acceptable.
Never turn timer knob to the left of zero.
* "Recommended Temperatures and Time Periods
(These times are
less than usual because these small
quantities of materials
autoclave require less time for steam penetration, and heating.)
HOW TO LOAD THE SPEED-CLAVE
Always cover bottom of trays with linen or paper towel, or light weight
muslin. Wrapped packs and instruments should be covered similarly.
INSTRUMENTS: For instruments, cover the bottom of each trav with
a towel of cotton or tissue. Instruments should be wrapped or covered.
It’s a good idea to put a drop of oil on moving parts of handpiece
(disassembled). Be sure to open all jointed instruments, such as scissors,
forceps, etc. Use instruments at once. Do not store them in the wrap-
ping in which they have been sterilized.
COTTON MATERIALS: Wrap cotton materials such as sponges,
rolls, gauze, cotton, points, etc., in a muslin compress or paper tissue.
An individual packet for each patient is recommended. Always cover
bottom of tray, and cover packs. See Castle Manual of Sterilization.
Don’t pack them tightly. Place deep or cylindrical jars on side— not
vertical— with cover off or loose.
DRYNESS: Cotton goods will be dry, if properly wrapped and
covered top and bottom. If condensation appears on instruments, press-
ing them with their cotton or tissue covering will remove it, and
their latent heat will complete the drying. Do not store instruments in a
damp covering. Sterile technique is best maintained by carrying instru-
ments in their covering to operating table for use as soon as cool.
Do not alternated autoclave and boil instruments, as that will cause
NOTES: Neon bulbs are Castle No. 3001 , available at vour dealers
or from Wilmot Castle Company. Their life is normally 3000 hours.
Air Vent (at rear). If the Air Vent at rear does not close at high alti-
tudes, write for special instructions.
